RADIORECQBD.

Application led April 7,

The ,objectief myfinvention isto provide la radio yrecord of .simple`and inexpensive construction, .which may .be usedby those einployingradio receivingsets for convenient'- lyy recording. .certain datainconnection with radio sending ,and reception in such manner that therecords will he quickly and easily accessible for reference. f

More particularly, it is my Object .t0 provide .airadio `record having aplurality :of series `of sheets arranged in superposed` relation andconveniently connected .together in a case.

Thisdevice .has ,a number of novel features v,of vc(instruct-ion .and.,arrangement, which facilitatetlie making Avof records rand .theconvenentreferlenee thereto.

.lVitlrthese .and ,other `objects.in view, my invent-ion `consists inthe construction, arrangement and VVcombinationof the various parts ofmyradio record, whereby the objects contemplated fare attained, lasherein- 'after more fully Aset vforth,,pointedout in my claims, andillustrated in the j accom- .panying drawings i in which;

YFigure 3 is a.A plan view of .the yrecord showingfanother. of VAthe`sheets ,adjuste ;l v to a ,ditl'erent 4position from the positionillustrated in ililigure 1; and: l Eigur-e 4F is ,a detail, sectionalview taken onatheline `of Figurel 2.

I My radio record includesA a Series of senil` circular sheets, .theseries being indicated generally bythe reference character A andthe-separate sheets vby the referencek nuigneial 10. These sheets are.superposedon each other, l-anda t Vthe central part oftheir sul-stan-tially straight ,edges are provided `'with the projections lOYLfor a pivot p :iiir'the like .11, by ywinch they are .connectedto-...gether-` in -superposed relation.

'Resting onthe seriesAis a second `series 'Bvoffsheets 12v ofthe saineshape but of Aslightly .shorter radius. The sheets 12 of the series Bare likewise mounted on the .pinpll x Extending circumferentially fromthe straightedgeof one side..O theslleets 10,

the sheets i are:` provided their outer edges iaa. serial No. 100,363.

with successive longer notches 13, 13a, 18b and so forth. `At theopposite sides, the sheets 12 are provided with radially eX- tendingtongues 14a, 14", 111C and so forth, which ,are lsuccessively longercircumferentially, or have theirlower edges ,spaced from an upper edgeat successively greater distances. f

Onthe sheets 10,011 the portions exposed through 'the notches 13 and Isoforth', AI mark index matter 15. Arranged inwardly from the'indexinatterv15 inradial lines on the sheets 12, l' arrange indicating matter 16,such for instance as the call letters of sending stations vand theaddresses of such stations. The circumferential columns thus formed may'be headed by the words Gall and Location' In the radial lines are leftspaces 17 lfor the insertion of dial readings, and the col-V umn ,formedby such spaces may be headed by the V.wordsDial reading.

On the tongues 14a and so forth, I arrange indexing matter, such forexample as the callletters ofcertain stations and radially inwardly fromthe indexing matter on the tongues .14a and so forth, I arrangeindicating matter 18, suchfor instance as call letters', addresses ofsending stations, the numerals indicating the wave meter length on whichsuchstations broadcast, andthe power' of the stations in watts.

rI he `circumferential columns, as thus formed, mayfbel headed, as showninFigure 3, by the words Location, lvVVave meters, Power watts, andYCall Supported on the pivotpin 1'1 and receiving .the sheets 12 andl()v is acasing comprising a topmembei 19,'bot'tom member .2O andaconnecting. wall 2l extending Vfrom one edge of the casing inwardlytoward the. center on one side vof the center only, shown in'lligure 1.Thus when the sheets k10 and 12 are all in superposed position, theirstraight edges on one side of the rcenter lfornied by ther pivot pinll'will snugly rest against` thel wall Av21.

ltwill-be noted that the casing portion 19 is of such radius las ,tolleave exposed the outer edges of the sheets 10 and the tongues 14a,etc., of the ,sheets 12. i

The utility of having the notches on the series of sheets A and and thetongues on the series ofsheets'Bisto enable a considerable number ofsheets to be indexed without making `the index members have other. Thisis accomplished by placing the diiilerent kinds substantially oppositeeach other.

Connected with the pin ll by means or" a string or the like 22 is apencil 23 for the convenience of the user of the record.

The portions ot the sheets l exposed below the notches 13 and so forthare provided with holes 2li, and the tongues lili and so forth areprovided with similar holes 25, which will receive the ysmall end ro'lfthe pencil 23 tor the convenience in manipulating the sheets.

ln the practical use oit' my improved radio record, the index matter l5is placed, as shown. For example, ll use the letters ot the alphabet,and then radially inwardly from the appropriate index matter, l placethe call letters oi the stations and the names ot such stations, comingunder the index matter on the particular sheet. Then as the dialreadings are ascertained, they may be placed on the proper sheet.

0n the tongues 14 and so forth ot the sheets 12 of the series B, placeindex inatter, such for instance as call letters, and then in the radiallines of the sheet, the address, call letters, wave length records andpower records.

One advantage or a record of this kind arises from the tact that it canbe completed by additions as the user may desire.

When it is desired to inspect the record, such inspection is easilymade. F or instance, it the user desires to look up the station at GrandRapids, Michigan, he refers to the index matter l5 under Gn puts the endot the pencil in the appropriate hole 24, and rotates the sheet Ytorexposing it. In the appropriate column, he i'inds Grand Rapids and thecall letters and the dial readings, it' they have been placed on therecord.

Similarly it the user has the call letter ot the station, and desires tolook up the data with regard to that station, he uses the point of thepencil 23, inserted into one of the holes in one of the tongues lea andso forth, tor moving one of the sheets 12 out of the pile, asillustrated in Figure 3, to make visible the data concerning location,wave meter length, and so forth.

lt will be noted that when the sheets are superposed in normal position,there is an imperforate portion ot a sheet below each hole, so that whenthe pencil is inserted into one hole for moving a sheet, it is stoppedby the next sheet, so that only the desired sheet will be moved out.

lin pushing the sheets back into position,

the wall 2l serves as a stop, so that they may all be easily andconveniently moved to position in the stack superposed one above theother. It also serves as a stop or gauge which is engaged by the edgesot the sheets, ior properly holding the indexes in alignment andvisible.

it will be seen that I have provided a record, which is 01"' a verysimple construction, to which data may be added from time to time as maybe desired, and which makes all oit the data readily available in aninexpensive compact device.

Some changes may be made in the details of the structure oit my radiorecord, without departing 'from the real spirit and purpose ot myinvention, and it is my intention to cover by my claims, any modifiedforms of structure or use of mechanical equivalents, which may bereasonably included within their scope.

claim as my invention:
